YASARA is powered by PVL (Portable Vector
Language), a new development framework that provides performance
way above traditional software. PVL allows you to visualize
even the largest proteins and enables true interactive real-time
simulations with highly accurate force fields on standard PCs, making use of GPUs if available (see
benchmarks). You can push and pull molecules around and work
with dynamic models instead of static pictures.

Being rooted in the academic world, all methods
introduced by YASARA are described in
peer-reviewed journals. You can obtain the initial stage 'YASARA View ' for free, while
higher stages (YASARA Model, YASARA Dynamics, YASARA
Structure) require a license fee
that allows us to guarantee new developments, updates and support
also in the future, independent of temporary grants. As a YASARA
user, you are not limited to the role of a consumer. If you decide
to share your developments with the community (macros, movies,
Python plugins or just feedback), you receive credits that in turn
give you free access to all stages of YASARA. Click

Since 2013, a touchable YASARA has been available
for mobile devices, and in April 2018, virtual reality with
head-tracking was released:

Unique YASARA features

In addition to a wide range of functions that can
partly also be found in other programs, YASARA provides a number
of features with unique properties:

With over 3500 citations, WHAT
IF is a widely used modeling program, well known e.g. for
its structure validation and prediction tools. The WHAT
IF / YASARA Twinset is a unified all-in-one distribution of
the two programs with extended functionality. If you run the
Twinset WHAT IF, an additional YASARA menu provides quick
access to molecular simulations. And vice versa, users of the
Twinset YASARA can simply run WHAT IF commands, so that WHAT IF
inherits YASARA's user interface, graphics engine, macro language
and convenience functions like unlimited undo/redo. This approach
makes WHAT IF quickly accessible, also to users outside the
bioinformatics expert community.
